What the World Eats by Faith D'Aluisio and Peter Menzel (amazon link) or Hungry Planet: What the World Eats by Peter Menzel and Faith D'Aluisio (amazon link)

These are listed as resources to supplement geography, and they have not been added to the weekly schedules.

How to use these books:
Leave them laying out, preferably near a globe or world map, and browse through them together from time to time.
Leave them laying out, browse through them and maybe once a month pick a country that especially interests your child. Look it up (briefly) on Wikipedia or in a good Atlas. Read a little bit more about it. Find it on a map or globe.
If your child is interested, he can pursue additional research in his free time and learn more about countries that particularly interest him, but this should be his own delight directed study or hobby.How not to use these books: as the basis of a unit study or a burdensome checklist of additional tasks to fulfill.

I looked through What the World Eats and I like it a bit better than Hungry Planet. They both picture families from around the world along with a week's worth of food, etc. IDK, I just like What the World Eats better. One may be a bit newer, as well.
